Preserve nonwhite background when using copy figure on macOS

I am trying to use a figure with a dark background in a presentation on Mac. I usually do this by using Edit -> Copy Figure and paste it into Preview or Keynote. However, this turns the black background into white. I know of the

InvertHardcopy = 'off'

requirement. It have set this option to off, it makes no difference.

How can I copy the figure just as it is, no fitting to an obscure page size, no changing colors, but preferably vectorized (screenshot being the last resort, obviously)

You can try:

copygraphics(gcf,'BackgroundColor','current')

Did you consider this already?

This is for Windows systems only. The 'programmatic alternative' is the InvertHardcopy, 'off' solution, which has no visible effects.

Thanks anyways
